Perform coordinated PM in the hypervisor using several sysfs interfaces
added to the hypervisor kernel.
- /sys/bus/pci/devices/X/power/coordinated
Writing "enter" to this file will cause the device to enter PCI
coordinated PM
Writing "exit" to this file will cause the device to exit PCI
coordinated PM
- /sys/bus/pci/devices/X/power/op_call
A write to this file will cause the device to perform a PCI PM
operation
- /sys/bus/pci/devices/X/power_state
A read from this file returns a snapshot of the device's current power
state, including PCI_D3cold
The guest makes use of these interfaces through a couple of
quick-and-dirty hacks in the PCI header in the guest.
- Byte writes to the "Revision ID" register are interpreted as PM op
calls
- Reads from the "BIST" register are interpreted as device PCI power
state
The PCI spec defines the "Revision ID" register as read-only. The "BIST"
register is mostly considered legacy and its use has not been observed
in recent Chromebooks.
The rest of the PCI config accesses remain the same.
This is only a temporary solution. A proper communication channel should
be implemented in the future.

Launching a VVU device requires access to /dev/vfio/$vfio_group. The
permissions on those files can't be set by upstart, since the files
don't exist until a vvu device process binds its vvu pci device to
vfio-pci. Instead, the permissions are set via udev rules.
Unfortunately, there is no good way to wait for udev to modify the
permissions, so the device process just needs to poll until it is
successfully able to open its device.

The size of the BAR limits the size of sibing VMs that can be used with
the vvu proxy device. Since concierge creates VMs with memory size a
little bit smaller than the amount of physical memory it sees, use the
CrOS guest's memory size for the vvu proxy device bar size. Since what
consumes memory is the mapping of sibling memory into the CrOS guest
(not the BAR itself), it's not necessary to strictly limit BAR size.

As part of the Windows porting effort, the virtio-block device was
changed to only report the VIRTIO_BLK_F_SEG_MAX feature on Linux, since
the maximum number of segments is based on the maximum number of iovec
entries supported by the system as reported by iov_max, which isn't
available on Windows.
Instead, we can support the VIRTIO_BLK_F_SEG_MAX feature everywhere, but
report that only one segment is supported on Windows. This results in
the same effective behavior for the Linux virtio-blk guest driver, which
assumes one segment if the feature is not supported, but it lets us
remove some platform-specific differences in the device and test code.

Use our new serde_keyvalue crate to annotate the
VhostVsockDeviceParameter config structure and allow us to create a
vsock device configuration from a key-values string. Add tests to make
sure parsing happens as expected.
Currently the vsock device is configured using the `--cid`,
`--vhost-vsock-fd` and `--vhost-vsock-device` command-line options.
While this CL introduces a way to set the vsock device up with a single
option (an ability we will eventually use), we retain the existing ones
for compatibility reasons.
BUG=b:218223240
TEST=cargo test -p devices vsock::tests::params
TEST=crosvm run with --cid parameter and check that virtio socket device
is present in the output of `lspci`.

When a vfio MSI-X vector got masked by guest, host vfio will release
the corresponding irqfd. Thus host device cannot trigger interrupt
via this fd and we then cannot set the pending bit. What we do instead
is to not release the irqfd but switch the registered kvm irqfd into
a new crosvm irqfd. So that when host device do trigger an interrupt,
crsovm will know about it and set the pending bit accordingly.
BUG=None
TEST=Pass through a nvme disk and tested its functionality.
